Make sure you have chosen the right size for your adsense. Have you applied adsense from your blogspot cpanel or you pasted the code from your adsense account?

 

There may be some other issues
Please provide the blog url so that we can say somthing.
Also check yourself, you didnot use any 'porn' words, copy righted contents etc

 

i have tried both ways but it is not appearing in homepage in both situation

 

how many ads you have on your home page

 

i have 3 ad links and one left sidebar add and inside post one and then right side one which is only not showing in homepage

 

What is your topic? Google adsens has ads on every topic, but I have seen some topics not being useful for getting ads..
